Sexual Dimorphism: Mystery Neurons Control Sex-Specific Behavioral Plasticity

Curr Biol. 2015 Dec 21;25(24):R1170-2. doi: 10.1016/j.cub.2015.11.002.


Sexual dimorphisms in the neurons and circuits of males and females control sex-specific behaviors that characterize each sex. A recent study describes a pair of newly discovered, male-specific neurons in C. elegans that control a sex-specific learning behavior termed sexual conditioning.
